Controller ft** iOptimise your Water Treatment using UV254 Measure several parameters from a UV254 sensor and connect via 4-20mA, which relays information to the control room. Dedicated relay can trigger the probe cleaning cycle. Applications Benefits Drinking Water and Wastewater: • Distribution system contamination • Source water monitoring /protection • Coagulation optimisation • Reverse Osmosis Industrial: • Food and Beverage • Commercial Aquaculture • Other industrial markets Real-time display of BOD, COD, TOC and DOC surrogates and direct measurements UVA, UVT, IRA, IRT and TSS Easy calibration of Probes Results every 10 seconds Intuitive user interface with 4 button navigation Password protected Optional datalogging up to 20 years Easy installation and placement IP66 housing suited for use outdoor installation Multiple mounting options Can be powered by mains or DC Low energy consumption (less than 5 watts) Power saving mode available Long range communication over 4-20mA Operates probe cleaning system www.photonicmeasurements.com Issue Date: October 2019 Measurement of surrogates requires routine calibration to standard procedures, as the water matrix chemistry may change with time. **Measurement of SUVA requires the probe to be periodically updated with the current dissolved organic carbon from the water.
